Doh, who'd have thought that IBM would describe in detail how a mac mini is perfectly suitable to be used as a linux based multimedia system that can be controlled from another computer via a web browser interface...

PowerPC G4 microprocessor. The motherboard is jumper-configurable from 1.25 to 1.58GHz (the jumpers are soldered), with the standard speeds from Apple being 1.25 or 1.42GHz. Find a link in Resources to a site with all the overclocking details you might want, if that sort of thing appeals to you. Overclocking is totally unnecessary for this application and I don't recommend it. The Mac mini is already frisky enough for everything you need to do.

Does that mean that the 1.42 is an overclocked 1.25 ?

Maybe it is because the Mini uses the IBM PowerPC Chip... The more Minis sold = more IBM chips sold... they are looking out for numero uno

They have also been pumping in lots of money into Linux. It's a double hit for them.

The article is on IBM's site, but the author isn't an IBM employee.

No it does not.

IBM doesn't make the Mac mini's G4. Freescale does.

In this months issue of Macaddict they show how to overclock the Mini. There are like 5 different speeds from 1.25 to 1.58....1.42 being on of them. All you have to do is change some small SMD resistors. Honestly since its only $100 to go to the next speed (and get a bigger hard drive) I would not be the least bit surprised if thats what they did (for profit margins).

Of course the magazine goes on to show how to put a 7200 RPM drive and more memory in too....and I'm think can 1.50Ghz, 7200 RPM drive and 1Gb of memory comfortably run off of an 85 Watt supply? Maybe

The 1.25GHz Mini uses 7447A1250s. The 1.42GHz Mini uses 7447A1420s. They are not overclocked.

Of course not. Nothing in the IBM statement indicates that in any way. Apple jumpers the motherboard to 1.25GHz when they put in a 1.25GHz CPU, and to 1.42GHz when they put in a 1.42GHz CPU. This is exactly the same thing that Apple has done since 1997 on every model that came in multiple speeds.

Right.

I just thought that they could be using 1 chip that is overclocked/downclocked to keep costs down, just one type of chip they need to buy.

Who's to say the 1.25 isn't an underclocked 1.42?

[Lateralus]

Why would Apple pay for and use a more expensive processor to underclock it? The 7447A comes out of Freescale rated at 1250 and 1420.

[tooki]

Apple has underclocked in the past -- though not by much.
